Abstract
Strict requirements for microclimate parameters and air cleanliness are imposed on warehouses, especially for food storage. Experience in the operation of storage facilities has shown the need for periodic dust removal of technological vehicles (electric cars and stackers), which is performed during maintenance by blowing compressed air and is accompanied by a strong dusting of the environment. In addition, the formation of fine dust in the pallet storage sections is observed.
The elimination of the noted drawbacks is effectively achieved by using activated exhaust hoods, which form weakly turbulent air jets that localize the source of pollution. To assess the effectiveness of the use of activated hoods, an integral method based on the laws of conservation of momentum, mass and energy was used. The example of a representative object illustrates the calculation of the parameters of activated exhaust hoods.
